Key Parameters

Substitute Part Grouping Explanation

Substitution of the LXY10VB331M8X12LL is determined by strict equivalence in the following core parameters:

Primary Equivalence Criteria:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 10 V (minimum; higher voltage ratings are acceptable as upgrades)
• Tolerance: ±20% (standard tolerance class)
• Polarization: Polar (radial aluminum electrolytic)
• Lead Spacing: 0.138" (3.50 mm) (PCB footprint compatibility)
• Mounting Type: Through Hole (mechanical compatibility)
• Package Type: Radial, Can (form factor compatibility)

Secondary Compatibility Parameters:

• Operating Temperature Range: -55°C ~ 105°C (functional envelope)
• Lifetime @ Temperature: 3000 Hrs @ 105°C (reliability specification)

Substitute parts are classified into two categories:

1. Direct Equivalents: Identical electrical and mechanical specifications with improved product status or compliance certifications.
2. Upgrade Substitutes: Higher voltage rating (16 V vs. 10 V) with identical capacitance and form factor, providing enhanced voltage margin while maintaining PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

ELXY100ELL331MH12D is the primary direct equivalent. This Chemi-Con part maintains identical electrical specifications (330 µF, 10 V, ±20%, 3000 Hrs @ 105°C) and mechanical compatibility (lead spacing, case diameter, through-hole mounting). The part is currently active in production and carries AEC-Q200 automotive qualification. Height difference of 0.059" (1.50 mm) requires PCB layout verification for clearance-constrained applications. RoHS3 compliance status provides regulatory advantage over the obsolete main part.

For Voltage-Upgraded Substitution:

UPW1C331MPD provides a 16 V rated upgrade while maintaining 330 µF capacitance and identical form factor. This Nichicon part offers lower impedance (117 mOhms vs. 170 mOhms) and higher ripple current capability (360.75 mA @ 120 Hz vs. 222.5 mA). Height is 0.453" (11.50 mm), providing 0.019" (0.50 mm) reduction compared to the main part. Product status is "Not For New Designs," indicating limited future availability. RoHS3 compliance is confirmed.

For Equivalent Voltage-Rated Substitution:

UPW1A331MPD is a Nichicon equivalent at 10 V rating with identical capacitance and tolerance. This part offers the same performance improvements as the 16 V variant (lower impedance, higher ripple current) while maintaining the original voltage specification. Height is 0.453" (11.50 mm). Product status is "Not For New Designs."

Selection Priority:

1. ELXY100ELL331MH12D for direct replacement with active product status
2. UPW1C331MPD for applications requiring voltage margin and improved electrical performance
3. UPW1A331MPD for equivalent voltage rating with improved electrical performance

Frequently Asked Questions (FAQ)

Q: Can ELXY100ELL331MH12D be used as a direct replacement for LXY10VB331M8X12LL?

A: Yes. Both parts share identical electrical specifications (330 µF, 10 V, ±20%, 3000 Hrs @ 105°C) and mechanical compatibility (lead spacing 0.138", case diameter 0.315", through-hole radial mounting). Height difference of 0.059" (1.50 mm) requires verification that PCB clearance accommodates the taller component.

Q: What is the difference between the main part and UPW1C331MPD?

A: UPW1C331MPD is rated at 16 V versus 10 V for the main part. Both maintain 330 µF capacitance and identical form factor. The 16 V rating provides additional voltage margin. UPW1C331MPD exhibits lower impedance (117 mOhms vs. 170 mOhms) and higher ripple current capability, resulting in improved thermal performance under AC ripple conditions.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: Lead spacing (0.138" / 3.50 mm) and case diameter (0.315" / 8.00 mm) are identical across all substitute parts, ensuring PCB footprint compatibility. Height variations range from 0.453" to 0.531" (11.50 mm to 13.50 mm). Applications with height constraints must verify clearance before substitution.

Q: Which substitute part has the best product status?

A: ELXY100ELL331MH12D carries "Active" product status, indicating current production and long-term availability. UPW1C331MPD and UPW1A331MPD are both classified as "Not For New Designs," indicating limited future support.

Q: Do all substitute parts meet RoHS compliance?

A: ELXY100ELL331MH12D, UPW1C331MPD, and UPW1A331MPD are all ROHS3 compliant. The main part LXY10VB331M8X12LL is RoHS non-compliant.

Q: What is the significance of AEC-Q200 rating on ELXY100ELL331MH12D?

A: AEC-Q200 is an automotive qualification standard. ELXY100ELL331MH12D carries this certification, indicating suitability for automotive applications with enhanced reliability requirements. The main part and other substitutes do not carry this rating.

Q: Can UPW1A331MPD and UPW1C331MPD be used interchangeably?

A: Both parts are mechanically and functionally compatible with the main part. UPW1C331MPD operates at 16 V while UPW1A331MPD operates at 10 V. Selection depends on circuit voltage requirements. The 16 V variant provides voltage margin but is not required for 10 V applications.
